Exercise 9 Page 141

Choose two ordered pairs from the table and calculate the slope by substituting them into the Slope Formula.

1/2

Practice makes perfect
Looking at the table, we can identify 4 ordered pairs. (-9,-2), (-5,0), (-1,2), (3,4) To calculate the slope of the line, we need only two of these. Let's find the slope by substituting (-9,-2) and (-5,0) into the Slope Formula.
m = y_2-y_1/x_2-x_1
m=0-( -2)/-5-( -9)
m=0+2/-5+9
m=2/4
m=1/2
